Anything Goes Martial Art
True. Gretzky was "The Great One" due primarily to his tremendous hockey IQ with enough physical ability including skating to execute what his mind read and anticipated on the ice. However, he was undersized and not really a two-way force. Mario Lemieux was and is still arguably the greatest hockey player of all time in terms of size and skill, but despite that, he wasn't really a two-way player either. McDavid, on the other hand, may be lacking in Gretzky's brains and Super Mario's size, but the dude is an effective and clearly a better two-way player, who also happens to have some of the fanciest skills in the modern era.That's a bold claim, and I don't mean the part about the GM. I think McDavid is an amazing player, and I'd easily give him top marks in his generation, but I'm still a Wayne fan when talking about talent, and Mario was pretty amazing too.
It remains to be seen who the greatest player of the trio will be but the odds are that title will rest with Gretzky, in part, because "The Great One" had better teams built around him. Mario's teams also qualified as better built rosters than what McDavid has had to go through in Edmonton. In terms of individual ability and effectiveness at both ends of the ice, I think McDavid has a legitimate claim to the title of "most talented".
